Reverse Digits Of An Integer In Python

Given a 32-bit signed integer, reverse digits of an integer. Example 1: Input: 123 Output: 321 Example 2: Input: -123 Output: -321 Example 3: Input: 120 Output: 21 Assume we are de

Solution 1:

Try converting the int to string, then reverse and then convert it to int.

Ex:

a = 1534236469
print(int(str(a)[::-1]))

Output:

9646324351

To handle the negative number:

if str(a).startswith("-"):
    a = a[1:]
    print("-{0}".format(int(str(a)[::-1])))
else:
    print(int(str(a)[::-1]))
